Are you using the Hungarian language pack that came with osTicket Awesome?
One easy way to fix this would be to open /index.php replace line 76…
<?php echo __('We provide archives and history of all your current and past support requests complete with responses.');?>
…with your own Translated text.
But I would be curious to take a look at your installation and figure out what the actual issue is, if you would be comfortable providing me with temporary access.
If so, please fill out this form with as much information as possible. (I won’t need an osTicket Administrator account for this, but I will need at least one connection method: cPanel/Plesk, FTP or SSH).
